Hoen- IMPROVEMENT IN ANIMAL POKS.

The Schedule referrer! to `in these Letters Patent and :making part of thesame.

To all whom it 'may concern:

Be itkuown'that I, WILLIAM KELLY, of Saranac,l

in the county of Ionia and State of Michigan, have invented certainl new and useful Improvements in improved arrangement of device, patented by me June A in the annexed drawings represents the yoke. b designates a roller, pivotedin the sides of yoke A. O isa bar, the np'per end of which is permanently secured to the center of roller b.

e represents a spring, the outer end of vwhich isfastened tot-he lower side of bar C, while theinnerend extends a little beyond the roller b.

Through the inner end of spring e the staple g is inserted, the said staple beingl made to pass through bar b, and playing loosely in the holes through which it passes.

nm-Had...-

At a suitable distance beneath roller b is placed the rod h, the ends oi' which are fastened in the opposite sides of yoke A. The object of' rod h` is to aiord a 'ulcrum for spring e.

The bar C, it will be seen, extends from yoke A at an angle of' about forty-five degrees, so that the outer end of said bar will come in contact with .a fence b efore the head of' the animal is near enough to disturb the rails.

The, moment a downward pressure is exerted on the outer end of bar C, the upward movement ot' spring ewill force the staple g in the same directionf and the pointed ends ot' the staple will prick the animals neck, and compel him to withdraw` from the fence.

Having thus described my invention, That-I claim, anddesire to secure by Letters Pat` ent,"is l i The arrangement of yokeA', rod h, b'ar e, staplel g, and roller l), substantially as herein shown and described.

In testimony that I claim the foregoing as my own I afiix my signature in presence of two witnesses.

WILLIAM KELLY. Witnesses:

CHARLES L. WILSON, WILLIAM Museen.
